Northern Illinois University freshman Antinette "Toni" Keller disappeared Oct. 14. The 18-year-old from Plainfield, Ill. was reported missing after telling her friends she was going to take a walk toward the Prairie Park in DeKalb. Human remains were discovered in the park a week after Keller was reported missing. Keller's disappearance is now a homicide investigation. But the remains found in the park where she was last headed are so badly burned that they can't be positively identified as Keller's.
